Good fun. Made life difficult for myself first time by having to use a trick to cross the two block sized hole after the ball, but realised that cant be intended way and got it right second time.
Very nice. There's a bit of instability in some of the falls, but you've adjusted the structures as best you can to compensate.
I really liked this level! Spoiler: Especially the double-use of the balls.not too hard and didn't require special tricks.
